BACKGROUND

1. Technical Field

The following relates to secure transmission of a message within a nodal network.

2. Related Art

Security of a message transmitted over the Internet from a first node to a second node of the Internet may be of concern. Thus the message may be encrypted to prevent an uninvited third-party eavesdropper from learning of the substantive content of the message. Unfortunately, the uninvited third-party eavesdropper may be sophisticated enough to access and encrypt the message. Thus, there is a need for improved security for protecting a message transmitted over the Internet from a first node to a second node of the Internet.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 depicts a nodal network 100, in accordance with embodiments of the present invention. The nodal network 100 comprises nodes 1-20, wherein any one of nodes 1-20 may communicate with any other of nodes 1-20 over a data communication path of the nodal network 100. The nodal network 100 may be of any communication medium type such as, inter alia, an Internet nodal network, a postal nodal network, a parcel nodal network a wireless nodal network, a vehicle communication network, an animal communication system, a multimedia nodal network, etc. An Internet nodal network may be embodied, inter alia, in an E-Mail communication system. A postal nodal network may be embodied in the United States Postal System. A parcel nodal network may be embodied in a package transport service such as, inter alia, United Parcel Service, Airborne Express, etc. A wireless nodal network may be embodied in, inter alia, a satellite communication system. A vehicle communication network may be embodied in, inter alia, message transport via taxicab, truck, train, boat, spacecraft (e.g., nodes may be distributed on different planets). An animal communication system may include, inter alia, message transport via horses, camels, donkeys, carrier pigeons, etc. A multimedia nodal network includes a plurality of communication media. In a multimedia nodal network, for example, communication between or among some nodes may be via the Internet, while communication between or among other nodes may be via the United States Postal System. In summary, the scope of the nodal network 100 of the present invention includes any and all communication media, individually or in combination.

The nodes 1-20 of the nodal network 100 may be located anywhere such as, inter alia: in a business office, in a residence, anywhere on the surface of planet Earth including on land or water (e.g., the Atlantic Ocean); in an airplane; ship, or spacecraft; underwater; underground; on any planet (e.g., Mars) of our local solar system; on any planet or other body in our galaxy, etc.

The messages of the present invention may be represented in any format or “modality” such as, inter alia, a text modality, a visual modality, an audio modality, or combinations thereof. The text modality denotes an expression of information in terms of written language (e.g., words, sentences, numbers, symbols, etc.). The visual modality includes, inter alia, a video modality (e.g., a feed or stream of video frames) and a graphics modality (i.e., synthetic imagery such as any synthetic graphics representation of information such as a graph, a pictorial bit pattern, etc.). The audio modality denotes an expression of information in terms of sound such as, inter alia, speech, music, etc. A message could include multiple modalities. For example, a first portion of the message could be expressed in a text modality and a second portion of the message could be expressed in an audio modality. As another example, a first portion of the message could be expressed in a text modality and a second portion of the message could be expressed in a visual (e.g., graphics) modality. If the message has multiple modalities then the different modalites could be transmitted from a first node to a second node over a same communication medium (e.g., the Internet) or over different communication media. As an example of transmission over different communication media, a first portion of the message expressed in a text modality could be transmitted over Internet nodes, while a second portion of the message expressed in an audio modality (e.g., expressed on an audio tape) could be transmitted over parcel nodes.

FIG. 1 illustrates transmitting a message from node 1 to node 2, with security protection by use of packetization and encryption. FIGS. 2A-2B, 3A-3B, 4A-4B, and 5A-5B illustrate how packetization and encryption may be combined, in accordance with embodiments of the present invention.

In FIG. 2A, a message M is packetized into message packets M₁, M₂, and M₃. Then the packets M₁, M₂, and M₃ are respectively encrypted into the encrypted packets M_(1E), M_(2E), and M_(3E). In FIG. 2B, the process of FIG. 2A is reversed such that the encrypted packets M_(1E), M_(2E), and M_(3E) are respectively decrypted into the packets M₁, M₂, and M₃. Then the packets M₁, M₂, and M₃ in FIG. 2B are synthesized into the message M.

In FIG. 3A, a message M is encrypted into the encrypted message M_(E). Then the encrypted message M_(E). is packetized into encryption packets M_(E1), M_(E2), and M_(E3). In FIG. 3B, the process of FIG. 3A is reversed such that the encryption packets M_(E1), M_(E2), and M_(E3) are synthesized into the encrypted message M_(E). Then the encrypted message M_(E). is decrypted into the message M. Note that an “encrypted packet” (e.g., M_(1E), M_(2E), and M_(3E) in FIGS. 2A-2B) results from packetization followed by encryption, while an “encryption packet” (e.g., M_(E1), M_(E2), and M_(E3) in FIGS. 3A-3B) results from encryption followed by packetization.

As shown in FIGS. 4A-4B and 5A-45B, use of encrypted packets or encryption packets for transmitting the message M from node 1 to node 2 may be structured such that all or some portions of the message M are encrypted. For example, if encrypted packets are used, all of the message packets M₁, M₂, and M₃ could be encrypted into the encrypted packets M_(1E), M_(2E), and M_(3E) as shown in FIG. 2A, but as an alternative message packets M₁ and M₂ could encrypted into the encrypted packets M_(1E) and M_(2E) while the packet M₃ remains unencrypted as shown in FIG. 4A, with the reverse process of reconstructing the message M shown in FIG. 4B. As another example, if encryption packets are used, all three encryption packets M_(E1), M_(E2), and M_(E3) could be generated as shown in FIG. 3A, but as an alternative the message M could be divided into an encrypted portion M_(E12) (such as, inter alia, by forming an unencrypted portion M₁₂ followed by encrypting M₁₂ into M_(E12)) and an unencrypted portion M₃ such that M_(E12) could be packetized into encryption packets M_(E1) and M_(E2) while unencrypted portion M₃ remains as unencrypted as shown in FIG. 5A, with the reverse process of reconstructing the message M shown in FIG. 5B. A packetization of the message M such as (M_(1E), M_(2E), and M₃), or (M_(E1), M_(E2), and M₃) is labeled herein as “hybrid packetization with encryption.”

Packetizing M_(E12) into M_(E1) and M_(E2) illustrate that an encrypted packet can be divided into at least two smaller encrypted packets. It is also within the scope of the present invention for unencrypted packets to be divided into at least two smaller unencrypted packets.

Although a message can be wholly expressed in one modality, packetization of a message lends itself optionally to a first message packet (encrypted or otherwise) of the message having content expressed in a first modality and a second message packet (encrypted or otherwise) of the message having content expressed in a second modality. The first modality could be a text modality, a visual modality, or an audio modality. The second modality could likewise be a text modality, a visual modality, or an audio modality provided that the second modality differs from the first modality.

Encryption may comprise single encryption or multiple encryption. A message packet is singly encrypted if it is encrypted once. A message packet is multiply encrypted if it is encrypted more than once. For example, a message packet that is doubly encrypted has been encrypted a first time according to a first encryption method or algorithm and subsequently encrypted a second time according to a second encryption method or algorithm.

Returning to FIG. 1, which illustrates transmitting a message from node 1 to node 2 with security protection by use of packetization and encryption, a message M at node 1 is packetized into the three message packets M₁, M₂, and M₃. The packet M₁ is transmitted from node 1 to node 2 via nodes 7 and 11. The packet M₂ is transmitted from node 1 to node 2 via nodes 8 and 12. The packet M₃ is transmitted from node 1 to node 2 via nodes 9 and 13.

Alternatively, any or all of the packets M₁, M₂, and M₃ could be transmitted from node 1 directly to node 2 without using any intermediate node in the transmission path from node 1 to node 2, such as the intermediate nodes 7 and 11 for transmission of packet M₁ from node 1 to node 2. Hence, a message transmitted from node 1 to node 2 is said to be “indirectly transmitted” from node 1 to node 2 when intermediate nodes are used in the transmission path from node 1 to node 2, and the message transmitted from node 1 to node 2 is said to be “directly transmitted” from node 1 to node 2 when intermediate nodes are not used in the transmission path from node 1 to node 2. Accordingly, “the word “transmitted” includes “indirectly transmitted” and “directly transmitted” as special cases. Similarly, a message received by node 2 from node 1 is said to be “indirectly received” by node 2 from node 1 when intermediate nodes are used in the transmission path from node 1 by node 2, and the message received by node 2 from node 1 is said to be “directly received” by node 2 from node 1 when intermediate nodes are not used in the transmission path from node 1 to node 2. Thus in FIG. 1, message packet M₁ is indirectly transmitted from node 1 to node 2, and indirectly received by node 2 from node 1, via intermediate nodes 7 and 11. Also in FIG. 1, message packet M₁ is directly transmitted from node 1 to node 19, and directly received by node 19 from node 1. Accordingly, “the word “received” includes “indirectly received” and “directly received” as special cases.

The packet M₁ could be replaced in FIG. 1 by an encrypted form as an encrypted packet (see FIGS. 2A-2B and 4A-4B, and accompanying description) or an encryption packet (see FIGS. 3A-3B and 5A-5B, and accompanying description).

If the packet M₁ is replaced in FIG. 1 by an encrypted packet, then packetization of the message M into packets M₁, M₂, and M₃ has preceded encryption into the encrypted packets M_(1E), M_(2E), and M_(3E). Such packetization of the message M has occurred at the node 1 and the packet M₁ could be encrypted into the encrypted packet M_(1E) at any of the nodes 1, 7, or 11. If M_(1E) is generated at node 1, then M_(1E) replaces M₁ in FIG. 1 between nodes 1 and 7, between nodes 7 and 11, and between nodes 11 and 2 (as well as between nodes 2 and 15, if relevant, as will be discussed infra). Similarly, if M_(1E) is generated at node 7, then M_(1E) replaces M₁ in FIG. 1 between nodes 7 and 11, and between nodes 11 and 2 (as well as between nodes 2 and 15, if relevant). Again similarly, if M_(1E) is generated at node 11, then M_(1E) replaces M₁ in FIG. 1 between nodes 11 and 2 (as well as between nodes 2 and 15, if relevant). Alternatively, each of M_(1E), M_(2E), and M_(3E) may be generated independently at 1, 7, and 11 such that M_(1E), M_(2E), and M_(3E) may be generated at the same node or at different nodes.

If the packet M₁ is replaced in FIG. 1 by an encryption packet, then encryption of the message M at the node 1 to generate the encrypted message M_(E) has preceded packetization at the node 1 to generate the encryption packets M_(E1), M_(E2), and M_(E3). Thus if the packet M₁ is replaced by an encryption packet in FIG. 1, then encryption packet M_(E1) replaces M₁ in FIG. 1 between nodes 1 and 7, between nodes 7 and 11, and between nodes 11 and 2 (as well as between nodes 2 and 15, if relevant, as will be discussed infra).

The preceding discussion relating to message packet M₁ and the associated encrypted packet M_(1E) as well as the associated encryption packet M_(E1) applies analogously to message packet M₂ and the associated encrypted packet M_(2E) as well as the associated encryption packet M_(E2), and also applies analogously to message packet M₃ and the associated encrypted packet M_(3E) as well as the associated encryption packet M_(E3).

In a “single-source” embodiment, the message M exists at node 1, because the message M is generated at node 1. In a “distributed-source” embodiment, the message M exists at node 1, because some or all of the message packets M₁, M₂, and M₃ are transmitted to from nodes 3, 4, and 5, respectively, as shown in FIG. 1 and in accordance with various alternatives. In a first alternative, the message packets M₁, M₂, and M₃ could be transmitted to node 1 from nodes 3, 4, and 5, respectively, followed by packetization and encryption of M₁, M₂, and M₃ to generate M_(1E), M_(2E), and M_(3E) as described supra, or followed by encryption and packetization of M₁, M₂, and M₃ to generate M_(E1), M_(E2), and M_(E3) as described supra. In a second alternative, the encrypted packets M_(1E), M_(2E), and M_(3E) could be transmitted to node 1 from nodes 3, 4, and 5, respectively, followed by transmission of M_(1E), M_(2E), and M_(3E) to node 2 by any of the nodal paths described supra. In a third alternative, the encrypted packets M_(E1), M_(E2), and M_(E3) could be transmitted to node 1 from nodes 3, 4, and 5, respectively, followed by trans mission of M_(E1), M_(E2), and M_(E3) to node 2 by any of the nodal paths described supra. In a fourth alternative, node 1 receives from nodes 3, 4, and 5 a combination of encrypted and unencrypted variants of packets M₁, M₂, and M₃ in analogy with the hybrid packetization with encryption described supra. In a fifth alternative, some but not all of M₁, M₂, and M₃ (or M_(1E), M_(2E), and M_(3E); or M_(E1), M_(E2), and M_(E3)) are generated at node 2 and a remainder of M₁, M₂, and M₃ (or M_(1E), M_(2E), and M_(3E); or M_(E1), M_(E2), and M_(E3)) are transmitted to node 1 from a subset of nodes 3, 4, and 5.

Thus for either the single-source embodiment or the distributed-source embodiment, the node 1 “gains” message packets by: generating of the message packets (at node 1); receiving (by node 1) the message packets from nodes 3, 4, and 5; or a combination of said generating and said receiving.

In FIG. 1, node 2 receives: the message packets (M₁, M₂, and M₃); or (M_(1E), M_(2E), and M_(3E)); or (M_(E1), M_(E2), and M_(E3)); or a hybrid packetization with encryption such as (M_(1E), M_(2E), and M₃) or (M_(E1), M_(E2), and M₃); etc. If node 2 has received all message packets associated with the message M, then node 2 may generate the message using all of said message packets. If all of the message packets received by node 2 are the encrypted packets M_(1E), M_(2E), and M_(3E), then the node 2 could generate the message M in accordance with the procedure described supra in conjunction with FIG. 2B; i.e., by decrypting M_(1E), M_(2E), and M_(3E) into M₁, M₂, and M₃, followed by synthesizing M₁, M₂, and M₃ into the message M. With hybrid packetization with encryption such as with M_(1E), M_(2E), and M₃ (see FIG. 4B), the preceding procedure is modified to decrypt only those packets that are encrypted, so that M_(1E) and M_(2E) would be decrypted into M₁ and M₂, followed by synthesizing M₁, M₂, and M₃ into the message M. If all of the message packets received by node 2 are the encryption packets M_(E1), M_(E2), and M_(E3), then the node 2 could generate the message M in accordance with the procedure described supra in conjunction with FIG. 3B; i.e., by synthesizing M_(E1), M_(E2), and M_(E3) into M_(E), followed by decrypting M_(E) into the message M. With hybrid packetization with encryption such as with M_(E1), M_(E2), and M₃ (see FIG. 5B), the preceding procedure is modified to synthesize only encryption packets, so that M_(E1) and M_(E2) would be synthesized into encrypted portion M_(E12), followed by synthesizing decrypting M_(E12) into unencrypted portion M₁₂ and synthesizing M₁₂ and M₃ into the message M.

While it is natural for node 2, as a destination of the message M, to decrypt message packets, any node of the nodal network 100 may decrypt a message packet. For example node 11 may receive message packet M₁ in an encrypted form (e.g., M_(1E) or M_(E1)) and then decrypt M_(1E) or M_(E1) into M₁, followed by re-encryption of M₁ into a different encrypted form, or followed by transmission of M₁ from node 11 to node 19 where M₁ is re-encrypted into the same encrypted form as previously or into a different encrypted form, followed by transmission of message packet M₁ (in an encrypted form) from node 19 to node 2.

After the message M is generated at node 2, a test at node 2 may be performed to determine whether M is really the message. An example of such a test is a “Make Sense” test which is an examination of M to determine whether M makes sense to a person, algorithm, machine, etc. If M makes sense then M is considered to be the message. M is considered as making sense to a person if M is intelligible to the person. M is considered as making sense to an algorithm if the algorithm processes the message as input, and is able to successfully execute and generate meaningful output. M is considered as making sense to a machine if the M is fed into the machine, the machine processes M, and the machine properly performs a function based on M (e.g., making a product that is a function of M). If M passes the Make Sense test then M is the message. If M does not pass the Make Sense test then M is not the message.

Another example of a test to determine whether M is really the message is an “Algorithmic” test, which performs a logical test on the message. For example, the Algorithmic test could be used to determine whether M contains a predetermined number of binary bits. As another example, the Algorithmic test could be to determine whether M includes a predetermined sequence of bits (e.g., “0011110101”).

In addition to generating M and determining that M is the message, the node 2 could send portions of M (e.g., M₁, M₂, M₃, M_(1E), M_(2E), M_(3E), M_(E1), M_(E2), M_(E3)) to other nodes of the nodal network 100, which could deter uninvited third-party eavesdroppers from knowing that the message M has been received at the node 2. This is illustrated by in FIG. 1 by transmission of message packets M1 and M2 from node 2 to nodes 15 and 16 respectively. Generally, any of M₁, M₂, M₃, M_(1E), M_(2E), M_(3E), M_(E1), M_(E2), M_(E3) could be transmitted from node 2 to any node(s) of the nodal network 100. Additionally for decoy purposes or for any other purpose, any given node of the nodal network 100 could send any portion of M that is accessible to the given node, to any node(s) of the nodal network 100. As an example, although node 12 is sending message portion M₂ (or alternatively M_(2E) or M_(E2)) to the node 2 which is the intended destination of the message M, node 12 is also sending message portion M₂ (or alternatively (M_(2E) or M_(E2)) to node 13 (for decoy purposes), and node 13 is sending message portion M₂ (or alternatively (M_(2E) or M_(E2)) to node 14 (also for decoy purposes). As another example, although node 1 (which may be the source of the message M) is sending message portion M₁ (or alternatively (M_(1E) or M_(E1)) to the node 7 for eventual transmission to node 2, the node 1 is also sending message portion M₁ (or alternatively (M_(1E) or M_(E1)) to node 19 (for decoy purposes).

A message packet can be killed at any node of the nodal network 100. For example, the message M and message packets M₁, M₂, and M₃ (or M_(1E), M_(2E), and M_(3E) ; or M_(E1), M_(E2), and M_(E3), etc.) could be killed at node 2 after the message M is generated. As another example, node 14 could kill message packet M₂ (or M_(2E), M_(E2), etc.).

Any node of the nodal network 100 may add content to a message packet which increases the size of the message packet. Any node of the nodal network 100 may delete content from a message packet which decreases the size of the message packet.

FIG. 1 shows dummy message packets D₁, D₂, D₃, D₄, D₅, and D₆. A dummy message packet is packet of information, data, etc., wherein the message M does not comprise the dummy packet. Each of said dummy packets may be encrypted or unencrypted. The dummy packet D₁ is transmitted from node 1 to node 2 via nodes 10 and 14. The dummy packet D₂ is transmitted from node 20 to node 1. The dummy packet D₃ is transmitted from node 2 to node 18. The dummy packet D₄ is transmitted from node 19 to node 3. The dummy packet D₅ is transmitted from node 3 to node 19. The dummy packet D₆ is transmitted from node 9 to node 1. Dummy packets serve to distract uninvited third-party eavesdroppers who desire to learn the content of the message M. The dummy packet D₁ at node 1 may be gained at node 1 by being generated at node 1 or by being transmitted to node 1 from another node of the nodal network 100. Any of the dummy packets D₁, D₂, D₃, D₄, D₅, and D₆ may be encrypted at any node having access to said dummy packets. Any of the dummy packets D₁, D₂, D₃, D₄, D₅, and D₆, if encrypted, may be decrypted at any node having access to said encrypted dummy packets. Any of the dummy packets D₁, D₂, D₃, D₄, D₅, and D₆ may be killed at any node having access to said dummy packets.

FIG. 6 depicts the nodal network 100 of FIG. 1 with true messages and dummy messages transmitted between nodes of the nodal network, in accordance with embodiments of the present invention. FIG. 6 illustrates transmission of a “true message” m₁ from node 1 to node 2, as well as transmission of “dummy messages” d₁, d₂, and d₃ from node 1 to node 2. A “true message” from node 1 to node 2 is a message intended by node 1 to be received and understood at node 2.

A “true message” in conjunction with FIG. 6 is analogous to a “message” in conjunction with FIG. 1. A dummy message in conjunction with FIG. 6 is a decoy message intended to distract an uninvited third-party eavesdropper from discovering the content of a true message. In FIG. 6, the dummy messages comprising d₁, d₂, and d₃ (and other dummy messages as will be identified and discussed infra) are intended to distract an uninvited third-party eavesdropper from discovering the true message m₁ and other true messages in FIG. 1 that will be identified and discussed infra. The idea behind the node 1 sending the true message m₁ and dummy messages (e.g., d₁, d₂, d₃, and also d₅ as will be discussed infra) is that an uninvited third-party eavesdropper attempting to discover or learn the content of the true message m₁ will be unable, or find it difficult, to distinguish between the true message m₁ and the dummy message. Thus, if many dummy messages are transmitted between nodes of the nodal network 100, the task by an uninvited third-party eavesdropper of attempting to discover or learn the content of the true message m₁ will be like trying to “find a needle in a haystack.”

For the subsequent discussion of FIG. 6 and for the claims herein, the terms “transmitted”, “directly transmitted”, “indirectly transmitted”, “received”, “directly received”, and “indirectly received” have the same or analogous meanings in conjunction with FIG. 6 as described supra in conjunction with FIG. 1.

In FIG. 6, node 1 transmits the true message m₁ from node 1 to node 2 via nodes 7 and 11. Alternatively, node 1 could directly transmit the true message m₁ from node 1 to node 2. Additionally node 1 directly transmits a true message m₂ to node 20, and node 1 indirectly transmits the true message m₂ to node 10 via node 20. While node 1 could generate true messages m₁ and m₂, node 1 could alternatively receive true messages m₁ and/or m₂ from other nodes of the nodal network 100. FIG. 1 shows that node 1 receives the true message m₁ from node 4, and also receives a true message m₃ from node 5.

Node 1 indirectly transmits the dummy message d₁ from node 1 to node 2 via nodes 8 and 12, but could alternatively directly transmit the dummy message d₁ from node 1 to node 2. Node 1 indirectly transmits the dummy message d₂ from node 1 to node 2 via nodes 9 and 13, but could alternatively directly transmit the dummy message d₂ from node 1 to node 2. Node 1 indirectly transmits the dummy message d₃ from node 1 to node 2 via nodes 10 and 14, but could alternatively directly transmit the dummy message d₃ from node 1 to node 2. Node 14 transmits the dummy message d₃ both node 2 and node 18. Node 1 directly transmits the dummy message d₁ to node 19, and indirectly transmits the dummy message d₁ from node 1 to node 7 via node 19. Node 1 directly transmits the dummy message d₃ to node 10, and node 1 directly transmits the dummy message d₅ to node 3. Node 1 receives the dummy message d₆ from node 6.

Any of the true messages and dummy messages transmitted and/or received by node 1 (or by any other node of the nodal network 100 may be encrypted.

Node 2 receives from node 1 the true message m₁ and the dummy messages d₁, d₂, and d₃ as described supra. Node 2 also receives dummy messages d₈ and d₉ from nodes 17 and 18, respectively. Node 2 transmits the dummy message d₁ directly to node 16, and indirectly to node 17 via node 16.

If the true message m₁ is encrypted, then node 2 may decrypt the true message m₁. Node 2 may distinguish between the true message m₁ and the dummy messages (e.g., d₁, d₂, d₃, d₈, and d₉) by such methods or techniques as, inter alia, a Make Sense test or an Algorithmic test, as described supra in conjunction with FIG. 1. Node 2 may read and/or interpret the true message m₁. Node 2 may retain the true message m₁, transmit the true message m₁ to another node (e.g., to node 15 as shown in FIG. 6), or kill true message m₁.

Any given node of the nodal network 100 may kill: the true message m₁; and/or any other true message accessible to the given node; and/or any dummy message accessible to the given node.
